Driving assist systems
nSounds and vibrations caused by the ABS
l A sound may be hea
rd from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi -
cate that a malfunction has occurred in this system.
l Any
of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
n EP
S operation sound
When the steering wheel operates, a motor sound (whirrin
g sound) may be
heard.
This does not indicate a malfunction.
n Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there
is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the engine off. The sys -
tem should return to normal within 10 minutes.
To help enhance driving safety a nd performance, the following sys-
tems operate automatically in res ponse to
various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
nABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

Before towing
Check that the following conditions are met:
lEnsure that your vehicle’
s tires are properly inflated. ( →P. 351)
l T
railer tires should be inflated according to the trailer manufacturer’s rec -
ommendation.
l All trailer light
s work to be legal.
l Confirm all light
s work each time you connect them.
l Check
that your vehicle remains level when a loaded or unloaded trailer
is hitched. Do not drive if the vehicle is not level, and check for improper
tongue load, overloading, worn suspension, or other possible causes.
l Make s
ure the trailer cargo is securely loaded.
lCheck
that your rear view mirrors c onform to any federal, state/provincial
or local regulations. If they do not, inst all rear view mirrors appropriate for
towing purposes.
n Break-in schedule
l T
oyota recommends that you do not use a new vehicle or a vehicle with
any new power train components (engine, transmission, differential,
wheel bearings, etc.) to tow a trailer for the first 500 miles (800 km) of
driving.
n Main
tenance
lIf you tow a trailer
, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.)
l Retighten the fixing
bolts of the towing ball and bracket after approxi -
mately 600 miles (1000 km).

168 2-5. Driving information
CAUTION
nTo avoid accident or injury
lThe total trailer weight (trailer weight plus the weight of cargo) must not
exceed 700 lb. (318 kg)
l Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
n Hitches
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be rated for towing a
higher weight, the operator must never exceed the maximum weight rating
specified for the trailer hitch.
lIf you wish to install a trailer hitch, your Toyota dealer should be consulted.
l Use only a hitch that conforms to the total trailer weight requirement.
l Follow the directions supplied by the hitch manufacturer.
l Lubricate the hitch ball with a light coat of grease.
l Remove the trailer hitch whenever y ou are not towing a trailer to reduce
the possibility of additional damage caused by the hitch if your vehicle is
struck from behind.
n When towing a trailer
lNever tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
l Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.

Trailer towing tips
Your vehicle will handle differently
when towing a trailer. The three
main causes of vehicle-trailer ac cidents are driver error, excessive
speed and improper trailer loading. Keep these in mind when towing.
l Before st
arting out, check the trailer’s light and the vehicle-trailer
connections. Recheck after driving a short distance.
l Practice tu
rning, stopping and revers ing with the trailer attached in
an area away from traffic until y ou become accustomed to the feel
of the vehicle.
NOTICE
n When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install the
trailer hitch on the bumper; this may cause body damage.
n Brakes
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
n Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
n Do not directly splice trailer lights
Directly splicing may damage your vehicle’s electrical system and cause a
malfunction.
